The German Society for Trenchless Technology advocates the pioneering trenchless technology that combines economic efficiency and environmental protection.

This modern approach for installing underground supply lines can be utilized for drinking water, wastewater, gas, heating, telecommunications or electricity lines.

GSTT's goal is to promote this modern technology that has been proven and tested worldwide over 30 years. Together with international partners, GSTT is continuously working on advancing the science and the practice of trenchless technology for the public and environmental benefit.

STREET TO HOME

For lateral relining from of the main pipe

The system allows inverting GRP-Liner against flow direction with open-end-method:

Positioning unit and inversion unit are placed into the main pipe (> DN 250 relined) from two opposing manholes. From there, after couplingof the units, the rehabilitationof the lateral (> DN100) is carried out.

CIPP – Lateral detector

Proceeding: An antenna is routed along the liner wall. The output signal of the sensor changes depending on the structure detected behind the wall.

PRM – Pipe Replacement Method

Bursting head

Widening

So far only pipe bursting and modified micro tunneling systems (pipe-eating method) are available for a pipeline

corridor, trenchless replacement of old pipelines.

pipe bursting pipe eating

A prerequisite to utilize this method isthat the surrounding ground can be displaced; major increases of dimensions are often problematic or impossible.

Pipe-eating method with guided auger system: set up 2.5 d, pipe eating 6.0 d, dismantling 1.5 d Σ 10 d

The new Invention method with short pipes*: set up 1.0 d, pulling process 2.5 d, dismantling 0.5 d Σ 4 d*for example polymer concrete jacking pipe

The new Invention method with PE Long pipes: set up 1.0 d, pulling process 1.0 d, dismantling 0.5 d Σ 2.5 d

A Tiny Circle - the Construction Pit of the Future

Where the keyhole technique is applied, surface damage and consequential costs only too well known from open trench installation methods are insignificant. The performance of soil and surface works is safer, more productive and less elaborate. Inspection of the construction pit is not required.

Application range: - installation of new property service

connections with non-directional GRUNDOMAT impact moles

- installation of new property serviceconnectionswith the directional drill rig GRUNDOPIT-K

- replacement of new property serviceconnections with the cable winchGRUNDOTUGGER

- sleeve sealing of cast iron and steel lines- repair of high pressure PE pipe lines- insertion of survey slots- pipe line inspection- corrosion protection sacrificial anodes

Keyhole-Technology + Trenchless Technique

Keyhole-Technology + Trenchless Technique

Establishing a keyhole using a core drill

• the core drill CD 650 bores a hole of 650 mm in diameter in the road surface. • after all other jobs are done, the bore core yielded in this working step is reinserted into the

road surface, fitting perfectly.• a suction excavator takes up the soil covering the main line• installation of the Pit K rig and performance of the bore with wall duct into the basement• connection with the main line is carried out above the surface.
